These two terms cause more confusion than anything else in translation. Here's a clear, simple explanation of what each means, when you need which, and what USCIS actually requires.
Certified translation = A translation accompanied by a signed statement from the translator (or translation company) certifying that the translation is complete and accurate. This is what USCIS requires.
Notarized translation = A certified translation where the translator’s signature on the certificate of accuracy has been witnessed and stamped by a notary public. USCIS does not require this, but some agencies and courts do.
Most people need a certified translation. Some people also need notarization on top of that. Almost nobody needs notarization without certification.
A certified translation is a translation that comes with a certificate of accuracy – a signed statement declaring:
This certificate is what makes a translation “certified.” Without it, the translation is just a translation – it has no official standing.
USCIS requirements (8 CFR 103.2(b)(3)): Any document in a foreign language submitted to USCIS must be accompanied by a full English translation that the translator has certified as complete and accurate, along with the translator’s certification that they are competent to translate from the foreign language to English.
Key point: USCIS does NOT require the translator to be “certified” by any specific body. There is no government-issued translator license in the United States. What matters is the certificate of accuracy – the signed statement accompanying the translation.
Cost at Corpus Localization: 8¢/word or $19.99/page (whichever is lower), including the certificate of accuracy.
A notarized translation is a certified translation with an additional step: the translator’s signature on the certificate of accuracy is witnessed and stamped by a notary public.
The notary does NOT verify the accuracy of the translation – a notary is not a translator. The notary only verifies the identity of the person who signed the certificate. In other words, notarization confirms “this person really did sign this document,” not “this translation is correct.”

For USCIS / immigration: Certified translation. That’s all USCIS requires. You can add notarization only if a recipient specifically asks for it.
For court: Check with your attorney. Some courts require notarized translations; others accept certified translations. When in doubt, ask the recipient whether notarization is required before ordering.
For university admissions or WES/ECE: Certified translation is sufficient.
For a foreign consulate: Check the specific consulate’s requirements. Many require notarized translations or even apostilled translations.
When in doubt: Get a certified translation. If you later find out you need notarization, we can add it to an existing order for $25.
“Notarized means more accurate.” No. Notarization has nothing to do with translation quality. The notary verifies the signer’s identity, not the translation’s accuracy.
“USCIS requires notarized translations.” No. USCIS requires certified translations (with a certificate of accuracy). Notarization is optional for USCIS filings.
“I need a certified translator.” There is no government-issued “translator certification” in the United States. What you need is a certified translation – a translation with a certificate of accuracy. Any competent translator can provide this.
“A notary can translate my document.” Unless the notary is also a qualified translator, no. A notary’s job is to witness signatures, not translate documents.
